The viral math trap that’s blowing up the internet: What’s the real answer to 7-2(8-4)?

You’ve probably seen it scrolling through your news feed. A seemingly simple equation: 7 – 2(8 – 4) = ?
The caption shouts, “Most people get this wrong!” or “The answer is NOT 6!”
The comments erupt in arguments: some say it’s 20 , others swear it’s -1 , and a few confidently claim it’s 6 .
So what’s really going on?
Why is a problem that seems like elementary homework causing chaos on the internet?
Let’s close the gap in the puzzle, apply the rules of mathematics, and uncover why people keep tripping over this puzzle.
🧮 The correct answer: Step by step
According to standard mathematical convention (PEMDAS/BODMAS), the correct answer is: ✅ -1
This is exactly why:

Step 1: Solve the problem in parentheses
8 – 4 = 4
The equation becomes:7 – 2(4)
Step 2: Handle the implicit multiplication
2(4) is the mathematical abbreviation for the expression 2 × 4.
Multiplication always occurs before subtraction.
2 × 4 = 8
The equation becomes:7 – 8

Step 3: Subtract
7 – 8 = -1
Final answer: Final answer:-1
💡 Key rule: In mathematics, a , such as , 2(4) has exactly the same priority as 2 × 4. It is not a separate operation that waits after subtraction. Multiplication (explicit or implicit) always precedes addition/subtraction.
